PURPOSE:To prevent the noise caused by the rubbing between a frame and a polyurethane layer by using a specific supporter material. CONSTITUTION:The airflow quantity of a supporter material is set to 5-300cc/ cm<2>/sec and the thickness is set to the range 0.6-10 mm essentially, and the range of a slant line section is preferable. The supporter material having the characteristic within the range formed by straight lines connecting four points indicated by coordinates (0.6, 5), (10, 5), (10, 300), (6, 300) is preferable, and the supporter material having the characteristic within the range formed by straight lines connecting four points indicated by coordinates (4, 50), (8, 50), (8, 200), (6, 200) is particularly preferable. The noise caused by the rubbing between a seat frame and a polyurethane layer can be prevented. |
